I think I may be looking for more layout flexibility than you offer. For example, for a rating scale question set, can I make the section header text larger and bold without changing the question and response scale text? They seem to change as one element. Can I move the section header text to the left of the response scale instead of above it?
You will not be able to make it a larger font, this will change the text in the entire field element. You can make it bold separetely though; you can also make it a different color, italic or underline.
